Api Call

API Call — DataPilot

Règle fondamentale

TOUS les appels API passent par src/lib/api.ts — jamais de fetch() direct dans un composant.

Structure de lib/api.ts

const API_BASE = process.env.NEXT_PUBLIC_API_URL ?? 'http://localhost:8000'

export function getAuthHeaders(): HeadersInit {
  const token = localStorage.getItem('access_token')
  return {
    'Content-Type': 'application/json',
    ...(token ? { Authorization: `Bearer ${token}` } : {}),
  }
}

async function request<T>(endpoint: string, options?: RequestInit): Promise<T> {
  const res = await fetch(`${API_BASE}/api/v1${endpoint}`, {
    ...options,
    headers: { ...getAuthHeaders(), ...options?.headers },
  })

  if (res.status === 401) {
    localStorage.removeItem('access_token')
    window.location.href = '/login'
  }

  if (!res.ok) throw new Error(await res.text())
  return res.json()
}

export const api = {
  dataSources: {
    list: () => request<DataSource[]>('/data-sources'),
    create: (data: CreateDataSourceDto) => request('/data-sources', { method: 'POST', body: JSON.stringify(data) }),
  },
  ai: {
    query: (question: string, dataSourceId: string) =>
      request<AiQueryResult>('/ai/query', { method: 'POST', body: JSON.stringify({ question, data_source_id: dataSourceId }) }),
  },
}
